Concern about Northern snakehead fish from China found in Maryland, US

source: New Scientist July 13 2002 p18

There is concern that Northern snakehead fish found wild in China could spread in the US, after one was found close to a pond in Maryland. The fish is a predator which can travel out of water, with the use of its pectoral fins. This fish is a predator, and is a metre long. The one found in Maryland could have escaped from an aquarium, or from a fish market. Maryland officials have asked members of the public to kill any of these fish they might find, because they could cause harm to the ecosystem.
